摘要:
A method and an apparatus for mapping a bit of an enhanced physical downlink control channel (e-PDCCH) in a wireless communication system are provided. A base station maps an e-PDCCH bit on a first region to which the e-PDCCH is allocated from a data region within a subframe, and maps a redundant bit of the e-PDCCH bit on a second region, which is between a control region and the first region within the subframe, including at least one orthogonal frequency division multiplexing symbol (OFDM). The e-PDCCH bit is mapped from a kth OFDM symbol within the subframe in the direction of an increasing OFDM symbol index, and the redundant bit is mapped from a (k−1)th OFDM symbol in the direction of a decreasing OFDM symbol index.

Provided are a method and apparatus for mitigating the interference of an interfering base station (eNB) in a heterogeneous network. The method comprises: transmitting threshold value information to an interfered eNB; receiving second feedback information, which takes into account interference caused by the interfering eNB to an interfered user equipment (UE) selected by the interfered eNB, from the interfered UE on the basis of the threshold value information and first feedback information; selecting a precoding matrix for minimizing interference to the interfered UE on the basis of the second feedback information; and applying the precoding matrix and transmitting a signal to an UE, to which the interfering eNB provides service.

Provided are a method and device for downlink control channel allocation in a wireless communication system. A base station allocates e-PDCCH (enhanced physical downlink control channel) to one slot in a subframe, and transmits a DMRS (demodulation reference signal) after allocating the DMRS to one of the slots for the e-PDCCH.

An interference elimination method performed by a first terminal in a multi-node system comprises the steps of: receiving information from a node on a second precoding matrix which is applied to a second signal to be transmitted to a second terminal; receiving from the node a first signal to which a first precoding matrix is applied; and eliminating an interference signal contained in said first signal on the basis of the information on said second precoding matrix.

The present invention relates to an apparatus and a method for determining a preferred component carrier (CC) to be used by a first station and a second station in a wireless communication system using a plurality of component carriers (CCs). According to the present invention, it is possible to lower inter-cell interference (ICI) with adjacent cells between the first station and the second station, and to improve the transmission efficiency. Further, the invention is capable of efficiently operating the plurality of component carriers.

The present invention relates to a disease diagnosing biosensor capable of promptly separating blood cells, in which a disease can be analyzed further accurately by adding a blood cell separating pad on a front or rear side of a capillary tube and separating the blood cells and plasma within 1 or 2 seconds owing to distribution of hydrophilic and hydrophobic segments. The entire configuration of the biosensor according to the present invention includes a base film; electrodes arranged on a top surface of the base film; a space film covering a top surface of the electrodes; a blood cell separating pad connected to a rear side of the space film; a capillary tube added on a rear top surface of the space film; and a cover film covered on a top surface of the capillary tube and the blood cell separating pad.
摘要:
A method for preventing carbon steel from intergranular cracking utilizing a reducing gas instead of nitrogen gas for a heat treatment of feeder pipes for a pressurized heavy water reactor (PHWR) nuclear power plant. This heat treatment protects carbon from oxidation to prevent the formation of decarburized layers so that the feeder pipes can be prevented from intergranular cracking. In addition, intergranular segregation of impurities is inhibited and intergranular strength of the carbon steel is enhanced. Therefore, no intergranular cracking occurs despite the concentration of stress.

Disclosed are a method and an apparatus for controlling an alarm function of a mobile device with an inertial sensor. In one example of the method, after an initial threshold value is established, an alarm occurrence is generated at a predefined hour. If the alarm occurrence is the first, an alarm control unit detects a first movement of the mobile device due to the alarm occurrence through the inertial sensor, and adjusts the initial threshold value according to the first movement. If the alarm occurrence is not the first, the alarm control unit detects a second movement of the mobile device through the inertial sensor, compares the second movement with the adjusted threshold value, and stops the alarm occurrence if the second movement is greater than the adjusted threshold value.
